I have Norton NIS running on a Lenovo laptop running Vista x64. There are two user accounts on it. Both accounts have the same settings including UAC on and are Administrator accounts.
Norton NIS 2009 will run on one account, but not the other (error 8504,4) even when the accounts are both logged on. Norton NIS somehow still runs in the background since I notice that LiveUpdate has been updating its definitions since I can see when NIS has updated on the other account.
I don't believe I need to reinstall NIS on this computer since it does work. I just want to know why this is happening.
